The housing stock
What we are usually working with in Hounslow Heath
The carry is the constraint: a single stair with tight half-landings, or deck access with a long walk from the lift. Socket positions, sill heights and wall flatness are the three things that settle this, and all three are properties of the building. A bowed wall gets measured at three heights first.
Estate roads with parking courts, bollards and tight turning heads, and some blocks are walk-up with access along an external deck.
The internal stair is usually a straight flight with a tight top landing, and it is the landing rather than the flight that is the limit. The carry is the constraint. Old fabric gets handled as old fabric.
What we are usually templating in is Postwar council-built house, 1960s maisonette and 1930s semi. The differences between them show up at template, not at enquiry.
There is nothing to visit in Hounslow Heath. Samples are posted free, the template is taken in your kitchen and the stone is fitted there too.
